Mutant strain of bird flu is spreading and it's resistant to existing vaccines, UN

Mutant strain of bird flu is spreading and it's resistant to existing vaccines, UN
Quote:Fears of a resurgence of the deadly bird flu virus have been raised by the United Nations, saying wild bird migrations had brought it back to previously virus-free countries.

A mutant strain of the disease is said to be spreading through Asia and at least eight people have died in Cambodia this year of bird flu.

The new strain of the H5N1 virus is spreading in China and Vietnam and can apparently sidestep defences of existing vaccines, the U.N. Food and Agriculture Organisation said in a statement yesterday.

It urged greater surveillance to ensure that any outbreaks are contained, although it is still uncertain though whether the mutant virus can be passed on to humans.

Last week, the World Health Organization reported that a six-year-old Cambodian girl had died on August 14 from bird flu, the eighth person to die from H5N1 avian influenza in the country this year.

Vietnam suspended its springtime poultry vaccination this year, FAO said.

Most of the northern and central parts of the country where the virus is endemic have been invaded by the new strain.

Elsewhere, FAO says bird migrations over the past two years have brought H5N1 to countries that had been virus-free for several years, including Israel, the Palestinian territories, Bulgaria, Romania, Nepal and Mongolia.

‘Wild birds may introduce the virus, but people's actions in poultry production and marketing spread it,’ said FAO's chief veterinary office Juan Lubroth in urging greater preparedness and surveillance.

WHO says globally there have been 331 human deaths from 565 confirmed bird flu cases since 2003 when it was first detected.

The virus was eliminated from most of the 63 countries infected at its peak in 2006, but it remained endemic in six countries: Bangladesh, China, Egypt, India, Indonesia and Vietnam.

The number of outbreaks in poultry and wild bird populations shrank from a high of 4000 to 302 in mid-2008, but outbreaks have risen progressively since, with almost 800 cases reported in 2010-2011, FAO said.

‘The general departure from the progressive decline in 2004-2008 could mean that there will be a flare-up of H5N1 this fall and winter, with people unexpectedly finding the virus in their backyard,’ Lubroth said in a statement.

But leading microbiologist, Professor Hugh Pennington, says that while there is no evidence that the flu is yet mutating to spread from person to person it is a 'reasonable speculation' that it has become resistant to Tamiflu - the main drug used in the UK to fight the virus.

The British and Scottish Governments spent over £100m on over 50 million doses of Tamiflu - enough for 80 per cent of the population

The emeritus professor of bacteriology at Aberdeen University had warned last year that deadly flu pandemics with special antiviral drugs could create an even more dangerous, untreatable 'superflu' after the UK expanded anti-viral stocks from 35 million to 50 million.

The Scottish government's effort to combat a possible pandemic is also heavily reliant on Tamiflu, an oral drug produced by the Swiss manufacturer Roche, despite warnings that it may be ineffective.

"Tamiflu should only be given to high risk cases. I think it is a reasonable speculation to make - given the new reports - that Tamiflu has been handed out inappropriately and the virus has developed a resistance to it. If that is the case that would mean that the UK's stocks of the drug would be largely ineffective,' said Professor Pennington.

'The idea that Tamiflu was a cure-all was plainly wrong.

'There is no need to panic yet because there is no evidence that the virus is spreading person to person and there are other anti-virals - such as Relenza - that do have an effect.

'There is also no evidence that the virus is becoming vaccine resistant. A new vaccine will have to be made, but that is to be expected. Flu is always changing and it would be staggering if this flu didn't. Vaccines have to be constantly updated.'

However, the UK Government has stockpiled only about ten million doses of Relenza and it is more difficult to take. While Tamiflu can be swallowed as a pill at home, Relenza is a powder that must be administered with an inhaler, normally under medical supervision.

But Professor Pennington warned that stocks of Relenza had to be increased. 'We have to get as much Relenza as possible because we don't know how effective Tamiflu will be,' he said.

'With flu the best advice is to prepare for the worst and hope for the best.'

Prof. Pennington, a past president of the General Society for Microbiology, said it was also 'impossible' to predict when this year's flu would strike.

Dr Steve Gamblin, the joint head of molecular structure at the National Institute for Medical Research, has also previously warned that the mutation renders Tamiflu about 250 times less effective than it should be.

Sir William Stewart, the chairman of the Health Protection Agency, has also said that the widespread use of antiviral drugs to treat illnesses, including bird flu and seasonal influenza, is causing- viruses to mutate into drug-resistant-forms.

He has claimed that drug-resistant viruses now represented as big a threat to public health as antibiotic-resistant superbug bacteria, such as MRSA.

Concerns that a pandemic flu virus might develop resistance to Tamiflu first emerged in 2005, after reports from Vietnam that H5N1 virus was showing signs of decreased sensitivity to the drug.

RE: Mutant strain of bird flu is spreading and it's resistant to existing vaccines, UN
great news eh... and one should always ask when they have a vaccine ready how long they knew or had been creating the original germ... @ least it's appearing to be contained in distant dirty shit holes so we all safe.... Riiiiight! Al la Dr Evil. with the lack luster protocols for international flyers all so worried about bombs the best terrorist weapon would be a super viriluant family from one of those shit hole countries, or a third party shipping point and boom the world could be sick in no time...

germs sux if you are in the city there inescapable, and in the rural area's many of us have animals who can even be ultra sensitive to some of 'em and then pass them on... germs more then anything could even be the bunker folks 's undoing and they know it the air systems they have are beyond impressive and are not just for making clean air but germ free air. course if there down there too long they will spawn a generation or two of super sanitary and germ vulnerable of spring, but if we surface folks who survive are dumb ass mutants guess they got the better end of the stick... i ramble lol...

Ever research (open knowledge) where you local germ testing places are, they are very well spread out and in the event of an earthquake or long term power outage these germs in many cases could be set free!!! just something to consider.

Remember Knowledge is the only thing THEY can't take from you, and Knowledge is Know how, and Know how is Power!!!

Live long and Prosper!!!! Have a plan beyond words, and worry not of why the storm is coming as to how you're going to survive in it!!!!
